The least witchy of all the ingredients is water, this simple wet substance makes a great base fluid for your potion. Pour in about 0.004 tons of juicy wet water.

Then add a bottle of tantermalè, but remember this innocent looking powder is deadly to humans. So be sure not to let any touch your eyes, mouth or knees.

Next poor in a whole peter bottle of fools' gold, which is also known as "Trump funds."

Then you'll need to add four shark's teeth from the mouth of a shark's mouth.

Lastly you'll need your time piece, I'm using a pocket watch. Gently lower the watch into the potion. Then give it a stir.

Then the magic will kick in and the temperature of the cauldron will drop to below zero degrees centrepoint (0.-02°C) and then your potion is ready.

Using some salad tongs, carefully remove the freezing watch.

Now, simply tap the watch face two times to freeze time. Tap it again and time will return to normal.

This potion is really useful for making your way through crowded streets, or when you get a message while you're right in the middle of doing something.
